Researchers characterize drug-resistant tuberculosis by analyzing the genomes of more than 500 Mycobacterium tuberculosis isolates from around the world.
Two genomic studies place the divergence of men from their most recent common ancestor nearer in time to that of women, though the field is far from a consensus.
Highways and byways are among the man-made environmental alterations driving the evolution of animals on contemporary timescales, with implications for ecology.
A sequencing study suggests that some genes have evolved in parallel in humans and their canine companions, likely as a result of shared selection pressures.
The root system of a tree species is genetically different than the leaves of that individual, potentially modifying scientists’ understanding of evolution.
